The FTerm AF aerial re-enterable fiber optic splice closure is designed for strand mounted applications. The FTerm AF closure can accommodate shielded or unshielded loose buffer tube or ribbon cables. The closure combines CommScope’ GelGuard sealing gel technology and FOSC fiber management systems. 4.0 Required Tools • • The FTerm AF closure can accommodate one cable up to 1.25” in diameter and two additional cables or up to eight small drop cables when grouped together up to .75” in diameter in each end of the closure. Flat head screw driver 216 tool (can wrench) 5.0 Mark and Open Cables Splice trays come with two SM12 splice modules which will hold up to 24 splices, provided that SMOUV splice sleeves are used (purchased separately, kit SMOUV-1120-01-US). 5.1 Mid-Span Cable Note: This closure is not recommended for load-bearing ADSS cable. Note: For loose buffer tube cable, it is beneficial to locate the reverse oscillation point and position it at the center of the opening. 2.0 Kit Components 2. Mark the cable 48” from the center in each direction. Ring cut the cable, and remove the jacket and shield, if present. • • • • • • • • • • • • • • 3. For loose buffer tube or ribbon cable, cut each strength member 4” from each sheath ring cut. (Figures 1, 2) 4. For core tube cable, remove all but 5” of central core tube at each end of the sheath opening. (Figure 2) 5. Clean exposed ribbons or buffer tubes with a clean cloth and company approved degreaser. 1.

Mark the center of the loop. 5.2 Grounding Shielded Cables The FTerm AF closure kit can be ordered in a grounded or ungrounded configuration. If the grounded kit is ordered, the ground straps are factory installed and ready to use. If the ungrounded kit is ordered but grounding is later required, order the AIR FOSC closure grounding kit and follow the installation instructions included with that kit. 2 Place approved bond clamps 90° from the top of the cables. To prepare shielded cables for grounding, install a B-bond clamp. Open a 1” slit in the sheath beyond the ring cut 90° from the top of the cables. Insert the lower portion of the B-bond under the shield with the stud protruding through the slit, and wrap with vinyl tape. Place the top plate over the stud and tighten it down with the nut. Recommended torque 40 in. lbs. Wrap the exposed area with vinyl tape. (Figure 3) 1'' Optional: slit in armored cable for bond clamp 4" 6. Open Housing and Hang Frame 1. 1'' Open housing using a can wrench to loosen the 3 bolts. To remove the frame grab the edge of the housing with your hands and push up on the bottom of the frame with your thumbs to release the frame from the housing. (Figure 4) Figure 1 Optional: slit in armored cable for bond clamp NOTE: Terminal cables should be added to the housing before re-attaching to the frame. This is best done while on the ground. Refer to section 10. 4" 2. Hang and secure the frame on the strand centering it over the midspan cable opening. 5" Figure 2 7. Attach Midspan Cable to Frame and Bond 1. Loosen the top bottle cap. Note: Do not use tape on cable sheath under hose clamp. 2. Slide the strength member(s) under the bottle cap washer; and continue pushing until the end of the strength member(s) is trapped under the lip of the frame. Tighten the bottle cap. (Figure 5) Figure 3 Note: If strength member(s) contain an outer jacket, it may need to be shaved off before fiberglass strength members will fit under the lip of the frame. Figure 4 Figure 5 3 3. Front View Place a large hose clamp around the cable and frame. Place a perforated metal square between the cable and hose clamp. (Figure 6) Tighten hose clamp to 40 in.lbs. Repeat for opposite end of splice opening. 8. Prepare Midspan Fibers for Splicing or Storage 8.1 Loose Buffer Tube (LBT) Cable Figure 6 1. Separate the buffer tube containing the fibers to be spliced from any remaining buffer tubes. Remove clear plastic cover from back of frame, or slide to one side. Push the unused loose buffer tubes through the window in the frame; push one side through first and let it “lead” the other side through so the buffer tubes don’t kink. 2. Coil and store the express buffer tubes using the 2” Velcro pads and 1/2” strips as shown in Figure 7. Be careful not to kink the tubes. Note: If cable storage is too large, tie wraps can be used in place of plastic cover. Do not overtighten the ties. 3. Re-position the plastic cover on the back of the frame. 4. Mark the buffer tube containing the desired fibers 23” from each sheath opening. Remove the buffer tube from the fibers between the marks per company-approved practice. Clean the exposed fibers with a clean cloth and company-approved degreaser. 5. Route the buffer tube along the top of the frame and down to the back side of the tray for attachment. Attach to upper holes with tie wraps. Recommended that you wrap one layer of loose buffer tube wrap around buffer tubes where tie wraps are used. (Figure 8) Back View Figure 7 Note: If buffer tubes are too stiff to route to the tray, remove the buffer tube and apply spiral wrap on the exposed uncut fibers to protect them, and route them to a splice tray for storage. 6. Cut a small piece of loose buffer tube wrap and wrap one layer around the end of each buffer tube where it will enter the splice tray. (Figure 8) Secure each buffer tube to the splice tray with two tie wraps. Note: Heads of tie wraps must face upwards on the tray. 7. Figure 8 4 Cut the fibers to be spliced and store the remainder on the tray. (See Figures 30A, 30B, and 30C for storage.) 8.2 Ribbon Cable Note: When using a tie wrap to secure central core tube to the frame, wrap the central core tube with LBT wrap first to prevent the tie wrap from crushing the core tube. IMPORTANT: Instructions for storing ribbon cable on the FOSC Ribbon Tray are included with the ribbon tray kit. The process is not covered in these instructions. 1. Secure the core tube to the frame with tie wraps through the holes in the frame. (Figure 9) 2. Identify the ribbon containing the fibers to be spliced, and separate it from the other ribbons. Remove clear plastic cover from back of frame, or slide to one side. Push the unused ribbons through the window in the frame and allow them to hang in a loop behind the frame. Hint: push one side through first, and let it “lead” the other side through so the ribbons do not kink. 3. Organize, coil, and store the uncut ribbons in the back of the frame using the 2” Velcro pads and 1/2” strips. Re-position the plastic cover on the back of the frame. (Figure 10) 4. Cut the ribbon containing the fibers to be spliced. If cutting the fibers dead-to-the-field, cut the ribbon as close to the field side (ONU side) of the splice opening as possible. If the fibers are part of a loop architecture, cut them in the middle of the splice opening. Transportation tubing must be used to route to tray for straight splice applications. 5. Figure 9 Back View Use a 16” section of transportation tubing and use it to protect the fibers from the selected ribbon. Route the encased fibers from the top of the frame to the back of the splice tray. Secure transportation tube to frame with tie wraps. (Figure 11) Figure 10 Note: If necessary, wrap the end of the ribbon with vinyl tape to make it easier to slide the ribbon through the spiral wrap. 9. Prepare Drop Cables for Splicing or Storage 9.1 LBT Drop Cables 1. Remove 48” of cable jacket. Mark and remove 25” of buffer tube. 2. Cut each strength member 4” from the sheath ring cut. Install bond hardware if applicable. See section 5.2. 9.2 Ribbon Drop Cables 1. Remove 55” of cable jacket. Remove all but 5” of core tube. 2. Cut strength members 4” from sheath ring cut. 3. Slide a 16” piece of transportation tubing over the fibers, extending 1” over the central core tube. Install bond hardware if applicable. See section 5.2. Figure 11 5 9.3 Attach Drops To Frame 1. Wrap the drop cable with a perforated metal square where it will be under the hose clamp. (Figure 12) Note: For multiple cables see Figure 12 for placement of metal square to prevent the cable jackets from slipping against each other under the hose clamp. 2. Slide cable and strength member(s) under the nearest bottle cap washer. Continue pushing until the end of the strength member is trapped under the lip of the frame, and tighten the bottle cap. 3. Place a small hose clamp around all drop cables and frame as shown in Figure 12. Tighten the hose clamp. 4. Cut a small piece of LBT wrap and wrap one layer around the end of each buffer tube. Place the drop fibers to the front of the splice tray. Figure 13 (see dotted line) depicts this procedure with loose buffer tube(s) cable. Secure the tube(s) to the tray with two tie wraps. 5. Attach the routing rings in any of the vertical holes shown in Figure 14 to keep buffer tubes away from hinge area. Figure 12 Figure 13 Figure 14 6 10. Connecting Termination Cables and Installing Pigtails 1. Unlatch and lift the terminal cover until it is in the locked position. (Figure 15) 2. Insert the pigtail(s) into the fiber duct. (Figure 16) 3. Plug in connectors 1 and 2 then adjust slack. (Figure 17) 4. Plug in remaining connectors as shown in Figure 18. 5. If needed readjust slack from the opposite side of the terminal. Proceed to step 5, next page. Figure 15 Figure 17 Figure 16 Figure 18 1 2 3 4 5 6 7 8 9 10 11 12 Figure 19 7 Figure 19a 1 2 3 4 5 6 7 8 9 10 11 12 Figure 19b 1 2 3 4 5 6 7 8 9 10 11 12 Figure 19c 1 2 3 4 5 6 7 8 9 10 11 12 Installing the Fanout 1. Attach breakout box with fasteners provided as shown in Figure 19a. 2. Insert the 36” transportation tube into the duct. (Figure 19) Insert fanout fibers into the transportation tube for routing to tray. 3. Plug in connectors . (Figures 19a, b, and c) 4. If needed readjust slack from the opposite side of the terminal. Drop 1 Drop 2 Figure 20 TracTape Caution: Check connector bend radius on terminal side. Note: If you have drop cables follow steps 5 and 6. If not, continue with step 7. 5. For a single drop cable apply a wrap of TRAC closure tape around the drop cable jacket 4” from the sheath ring cut. 6. For multiple drop cables that will share a port in the end piece, wrap a layer of TRAC closure tape between the drop cables and around them starting 4” from the sheath ring cut, as shown in Figure 2. Do not exceed .75” total diameter in any single port. 7. Install the end pieces around the cables, with the end piece closure tab facing forward. (Figure 21) Install cable spacers per company practice on either side of the closure so that the cables are spaced properly and parallel to the strand as they enter the end pieces. 8. Wrap the closure housing around the frame with the bolts facing up. Place the body over the top two tabs of the frame, and press the bottom two tabs into the opening of the housing until they snap in place. (Figure 22) Figure 21 Figure 22: Cutaway Side View 8 9. On the front side place the bundle of pigtails or transportation tubing under the pre-installed LBT or ribbon present on the right side. (Figure 23) and over the pre-installed tubes attached on the left side if present. (Figure 24) 10. Hold the pigtail bundle on the tray and mark the yellow tubing one inch from the end of the tray. (Figure 25) From the mark, measure out 22” for pigtails and fanout if de-ribbonized and cut off evenly. Alternatively, if using ribbon tray, from the mark measure out 35” for fanout. Ribbon cannot be stored on a single tray, slack will have to be pulled into the back of the frame. Note: The length to the tray mark will be approximately 25” from the fiber duct. Figure 23 Figure 24 Figure 25 9 12. Cut and remove the yellow tubing and aramid fiber strands from the mark. (Figure 26) 13. Wrap a piece of LBT wrap around the bundle of the pigtails or transportation tube if using fanout. Remove tray and attach pigtails or transportation tube with two tie wraps as shown in Figure 27. 11. Splice Fibers and Store on Tray Note: If kit contains a ribbon tray; follow ribbon tray instructions. Fiber routing should follow the embossed arrows on the tray. (Figure 28) Figure 26 Do not store ribbon slack on single tray; pull ribbon slack from the tray to the slack basket. See Figure 29 for routing and splicing ribbon to ribbon cable. Figure 27 Figure 28 Main Drop Figure 29 10 Figures 30a, 30b, and 30c illustrate examples of proper fiber routing, though other arrangements are possible. Figure 30d illustrates improper fiber routing. Drop Cable Fibers Main Cable Fibers: Note: It is helpful to pre-organize your fibers on the tray prior to splicing to determine the right configuration; routing should match one of the diagrams in Figure 29 or 30a, b, or c. Drop fibers Figure 30A Main cable fibers Figure 30B Figure 30C WRONG! Both of these patterns will cause signal attenuation! Figure 30D 11 For easier splicing, remove tray from tray bracket, close bracket, cut 1” squares of both Velcro hook and eyes and join together. Remove release paper from both sides and attach to frame. (Figure 31 ) Position tray over the top of the Velcro fastener and press in place. (Figure 32) When all splices have been completed and stored, install plastic tray tabs on the arcs to help hold down the fibers. Replace the clear plastic tray cover. 12. Install Closure Body 1. 2. Wrap the black Velcro fastener strap around the tray and tray holder to keep the tray(s) in place. Lift the tray bracket so that it hinges and snaps closed against the frame. Avoid pinching ribbons, buffer tubes, transportation tubes, etc. in the bracket. Figure 31 Close the housing, making sure the ends align properly with the end pieces. Fasten the supplied bolts to secure the body in place. (Figure 33) Figure 32 Figure 33 AIR FOSC, FTerm, GelGuard, SMOUV, TRAC, CommScope logo, and CommScope are trademarks.
